It was your response I took umbrage at, not your lack of knowledge on “PC matters” (whatever that has to do with anything). It’s a lot easier to give “have you tried this” suggestions if you tell us what you’ve already tried, otherwise we’ll be here for a fortnight playing twenty questions.
If it’s Hotmail, the Hotmail app from the Market should ‘just work’ without needing settings configuring; indeed, you say you’ve changed settings, which makes me wonder how, cos I didn’t think there were any. Though in honesty I’ve not explored it in depth, so I don’t know for sure whether it has any other prerequisites.
You could also try just adding the Hotmail account in Settings / Accounts, or using webmail if all else fails.
